Additive for gasoline and diesel fuels

Claim 1

THE METHOD OF MAKING AN ADDITIVE SUITABLE FOR A SPARK IGNITION ENGINE HYDROCARBON FUEL BOILING IN THE GASOLINE BOILING RANGE AND FOR A DIESEL ENGINE FUEL, WHICH COMPRISES ADMIXING SUBSTANTIALLY DRY UREA AND A DRY ALKALI METAL HYDROXIDE SELECTED FROM THE GROUP CONSISTING OF SODIUM HYDROXIDE AND POTASSIUM HYDROXIDE WITH A LIQUID MIXTURE CONSISTING ESSENTIALLY OF AN ALCOHOL CONTAINING FROM THREE TO FIVE CARBON ATOMS, A KETONE CONTAINING UP TO SIX CARBON ATOMS AND A SOLVENT SELECTED FROM THE GROUP CONSISTING OF A PETROLEUM DISTILLATE FRACTION HAVING AN A. S. T. M. DISTILLATION WITH AN INITIAL BOILING POINT WITHIN THE RANGE OF ABOUT 210*F. TO 335* F., AN END POINT WITHIN THE RANGE OF ABOUT 240*F. TO 415*F., AN A. P. I. GRAVITY WITHIN THE RANGE OF ABOUT 27.5 TO 42.5 AT 60/60*F. AND AN AROMATIC HYDROCARBON CONTENT ABOVE ABOUT 50%, BENZENE, A HOMOLOG OF BENZENE, GASOLINE AND KEROSENE, THE AMOUNT OF SAID UREA BEING WITHION THE RANGE OF FROM ABOUT 5% TO 15% OF THE WEIGHT OF SAID LIQUID MIXTURE, THE AMOUNT OF SAID ALKALI METAL HYDROXIDE BEING WITHIN THE RANGE OF FROM ABOUT ONE-SIXTH TO ONE-HALF OF THE WEIGHT OF SAID UREA, THE SAID SOLVENT COMPONENT OF SAID LIQUID MIXTURE COMPRISING FROM ABOUT 25% TO ABOUT 75% BY VOLUME OF SAID LIQUID MIXTURE, AND THE ALCOHOL AND KETONE COMPONENTS COMPRISING EACH IN EXCESS OF ABOUT 10% BY VOLUME OF SAID LIQUID MIXTURE, ALLOWING THE ADMIXTURE TO STAND AT ORDINARY ROOM TEMPERATURE UNTIL A CLEAR REDDISH COLORED LIQUID IS FORMED, AND SEPARATING THE RESULTANT CLEAR RED LIQUID FROM ANY NEWLY FORMED SOLID MATERIAL AND RESIDUAL MATERIAL.
